About Me

I’m a computer science student with experience in full-stack engineering, software development, and AI/ML implementation. My work spans full-stack application design, LLM AI systems, and creative C# desktop apps and automation projects that solve everyday problems.

Projects

Fullstack Secure Password Manager

Built a fullstack password manager web app using Flask and CryptoJS.

Real-Time CV-to-Game Control Pipeline

Real-time obstacle game with Pygame and MediaPipe hand-tracking to detect gestures to control movement.

Retrieval-Augmented Personal AI Chatbot

Architected a RAG pipeline using sentence-transformers to vectorize a curated dataset of Q&A pairs, enabling grounding for an AI assistant.

About This Chatbot

This RAG (retrieval-augmented generation) Chatbot was architected using FastAPI to serve asynchronous endpoints and an endpoint handling prompt engineering and prompt augmentation.

Vector embedding and cosine similarity is used to identify a similar prompt-response pair to augment OpenAI's GPT-5-Nano model with special prompt engineering.

This enables utilization of personalized data about me without fine tuning alongside the natural language generation of GPT-5-Nano technology.
